Tunable Plasmonic – Photonic Hybrid Structure

A highly tunable plasmonic – photonic hybrid structure is proposed in this paper. Selecting different geometricalparameters for the hybrid structure with variation less than 30 nm, we demonstrate that the various optical resonancesranging from 1.45 μm to 1.55 μm are achieved with a huge optical field intensity originating from combined modes ofresonators. The proposed coupled structures are directly applicable in diverse domains such as nonlinear optics, datastorage, lasers, deeply subwavelength intense optical sources, sensors, etc.
